Emergency Vehicle Service

Chassis Service

The Chassis B Service is your apparatus's annual comprehensive health assessment—a rigorous, systematic inspection that covers 78 critical points across every major system that keeps your rig road-ready and mission-capable. Our certified technicians examine the cab interior for safety and operational integrity, assess the exterior body for structural soundness and corrosion, and thoroughly evaluate the drivetrain to catch wear before it becomes failure. We test all electrical systems and lighting for full NFPA compliance, inspect tires for tread depth, wear patterns, and proper inflation, and document every finding with detailed reporting. This isn't a quick walk-around; it's a preventative investment that protects your crew, extends apparatus life, and ensures your department ready.
